Hey guys,

I have a problem with my PC constantly locking up. It is happening at different moments so I have no idea what is causing it... sometimes it happens while I'm playing a game but it can also happen just after start up on the desktop with nothing opened yet.
Sometimes I can play a game for a long time without any problems at all and the other time it locks just after starting something up.
So I don't think it is a heat problem or a problem with my graphics card. I myself am thinking about a problem with my power supply (though I put in a new one not long ago). These problems started since 2 weeks or so, I don't recall installing anything special. It locks up maybe 3-4 times a day now, sometimes two times in a row. So I can still live with it but it is starting to annoy me by now... .

Any idea what may be causing this? Or are there any programs I could run to see if it is any of my hardware giving problems?

I allready ran different Virus, spyware and adware programs and no problems there.

Help is much appreciated!

And of course here are my specs:

Intel Core 2 Duo E6750 @ 2.66GHz
Asus PK5-VM S775
4GB DDR2 PC6400 800MHz
GeForce 8800GTS 320MB (PCI-E)
2X Seagate 250GB 16MB SATAII
Creative SB Audigy SE

The power supply is 350 Watt and I am running Vista Home Premium (Dutch).
